1 Claim. (Cl. 297-443) Matter enclosed in heavy brackets appears in theoriginal patent but forms no part of this reissue specification; matterprinted in italics indicates the additions made by reissue.

My invention relates generally to foldable and disposable chairbacksupported seating structure for babies, t.g. [infant seats] stands ofthe type disclosed in Patent 2,324,421, and more particularly torelatively inexpensive disposable devices of this character.

The primary object of my invention is the provision of an infant [seat]stand of the type immediately above described which may be formed from ablank of relatively tough paper stock such as corrugated paper board.

A further object of my invention is the provision of a device of theclass immediately above described which is extremely inexpensive toproduce and which is sufiiciently rugged and durable in construction toendure the stresses and strains of normal use for the relatively briefperiod of time for which it was constructed.

A further object of my invention is the provision of a device of theclass immediately above described which, while inexpensive to produce,may be utilized with all the benefits derivable from a more expensiveand permanent structure of this type.

A further object of my invention is the provision of a device of theclass above described which is extremely light in weight and henceextremely easy to handle, store and ship.

The above and still further objects of my invention will become apparentfrom the following detailed specification, appended claim and attacheddrawings.

Referring to the drawings wherein like characters indicate like partsthroughout the several views:

FIG. 1 is a view in top plan of a blank of corrugated board or the likescored and folded in accordance with my invention;

FIG. 2 is a view in perspective showing partial formation of my novelstructure from the blank of FIG. 1;

FIG. 3 is a perspective view on a somewhat reduced scale showing mynovel structure in complete and operative condition;

FIG. 4 is an enlarged fragmentary sectional view taken on the line 4-4of FIG. 3;

FIG. 5 is an enlarged fragmentary view taken on the line 55 of FIG. 2;and

FIG. 6 is a fragmentary view in rear elevation of the structure of FIG.3.

Referring with greater particularity to the drawings, the numeral 1indicates in its entirety a blank stamped from corrugated paper boardstock and folded and scored to provide a back element 2, side wallmembers 3 secured to opposite side edges of the back element 2 alongfold lines 4, and top and bottom wall members 5 and 6 securedrespectively to the upper and lower edges of the back element 2 alongfold lines 7 and 8 respectively.

Side wall members 3 are shown as comprising matching inner and outersections 3a, 3b which are connected together along central fold lines 9.As shown, each of the sections 3a, 3b taper from their relatively widelower edges 10 to their relatively narrow upper edges 11, whereby todefine upwardly tapering side walls, as shown in FIG. 3, when the innersections 3a are folded inwardly upon the outer sections 3b, along foldline 9, and the side wall members 3 swung at right angles with respectto the back 2 along the fold lines 4. To maintain the side wall members3 in this operative position, the free outer edges 12 of the inner sidewall sections 3a are formed to provide tabs 13 which are insertable intoopenings or recesses 14 on opposite sides of the back element 2.

The top wall member 5 likewise comprises matching inner and outer wallsections 5a, 5b respectively which are foldable along the line 15. Asshown particularly in FIG. 1, the inner section 5a is formed to providetabs 16 along its free outer edge 17 which are adapted to be receivedwithin apertures or recesses 18 adjacent the upper edge of the backelement 2, as defined by the fold line 7. The adjacent opposite sideedges 19 of the outer sections 3b of the side wall members 3 areprovided with flaps 20 receivable between the inner and outer wallsections 5a, 5b of the top wall member 5 for the purpose of securelylocking the top wall member 5 to the side wall members 3 in theiroperative positions of FIG. 3 wherein they project at right angles tothe plane of the back element 2. Any suitable adhesive may be utilizedfor securing the elements 5a, 5b and 20 together.

The relatively deep bottom wall forming member 6 likewise comprisesinner and outer matching wall sections 6a, 6b, the free outer edge 21 ofthe inner wall section 6a having tabs 22 receivable in apertures orrecesses 23 in the back-forming element 2, when the bottomformingelement 6 is placed in operative position by bending the same at rightangles in the plane of the backforming element 2, along fold line 8. Theadjacent opposite side edges 24 of the outer side wall members 3b arelikewise formed with flaps 25 which are receivable between and rigidlyadhered to the inner and outer wall sections 6a, 6b, to lock theseelements together.

To anchor my novel infant [seat] seating structure in a generallyupright position to a suitable vertical support, as shown in FIG. 3, Iprovide a tie member 26 which projects through laterally spaced openings27 in the back element 2. For the purpose of securing an infant withinthe forwardly opening [seat] seating structure, I provide an adjustablegirth strap 28, opposite ends of which project through laterally spacedopenings 29 in the back element 2 intermediate the upper and lower endsthereof. The extreme outer ends rearwardly of the back element 2 areknotted or otherwise enlarged to discourage their being pulled throughthe openings 29. The intermediate portion of the girth strap 28 issecured to the upper end of a crotch strap 30, the lower end of which islooped through an opening or aperture 31 in the bottom wall member 6intermediate the sides thereof. As shown the aperture 31 is formed byalignable apertures 31a, 31b in the inner and outer wall sections 6a, 6band by alignable notches 31c in the opposed adjacent edges 32 of theflaps 25.

The method of use of my novel disposable infant [seat] seating structureabove described is identical with that described in Patent 2,324,421,and as there shown any desired arrangement of cushions or pads,disposable or otherwise, may be placed in engagement with the backelement 2 and the bottom wall member 6.

My invention has been thoroughly tested and found to be completelysatisfactory for the accomplishment of the above objects, and while Ihave disclosed a preferred embodiment it should be understood that samemay be capable of modification without departure from the scope andspirit of the appended claim.

What I claim is:

A foldable and disposable chairback supported [seat] seating structurefor infants, comprising a one-piece foldable blank having asubstantially rectangular back wall portion adapted to be mounted on andrest against said chairback, sidewall portions substantially coextensivewith and foldzibly connected to opposite sides of said back wallportion, each said side Wall portion being obliquely folded upon itselfsubstantially midway between its longitudinal outer edge and itsfoldable connection with said back portion and extending normal theretoto provide a reenforced [seat] bottom suspending means, foldable endwall portions extending normal to and beyond one end of each of saidside and back wall portions with said side end wall portions disposed insuperimposed relation to said back end portion and providing areenforced [seat] bottom suspended between said folded side portions,and means interconnecting said folded side and superimposed end wallportions to said back wall portion and said back wall portion to achairback.
